Application filed September 25, 1918. Serial No. 255,626.

county of Barton and State of'Kansas', have invented certain new and useful Improve- .ments in Stock-Releasing Devices, of which the following is a specification, reference being. had to'the accompanying drawings.

This invention relates to an improved stock releasing device, and has for its primary object to provide means for quickly releasing the animal from a stall in case of fire, the releasing means being operable from the exterior of the stall and at each side thereof.

It is another and more particular object of my invention to provide a device for th;

ro extending through the series of stal s, adjacent the inner faces of the front walls of the mangeraspaced -means on the rod to coact with means attached to the halters.

, of the animals, whereby the halters are locked to the respective mangers, and means connected to each end ofsaid rod and operable from the exterior of the barn whereby struction, combination and relative arra ment of the several the rod may be axially shifted to release the I halters.

It is another one of the detail ob ects of the invention to provide im roved means for preventing the casual, s ifting movement of the rod by the tugging of the animals on. the halters WhlCh might efiectthe release of the lattera It is also another important object of the invention to provide means for insuringthe free and easy operation of the locking means so that the halters will be instantly released upon the actuation thereof..

It is also a further general object of my invention to provide a device for the above purpose whichis simple-and durable in its construction, highly eflicient and serviceable in practical use, and capable of manufacture at relatively small cost.

With the above and other objects in .view, the invention consists in theimproved con- 8- arts as Will'be here1nafter more fully escribed, subsequently claimed and illustrated in the accompany-- for a proved stock releasing means applied to a series of mangers;

Fig. 2 is a horizontal section taken on the line 2 -2'of Fig. 1;

Fig. 3 is a vertical section taken on the Iine'33 of Fig. 1; Fig. 4 is a pers of the halter loc position; and t Fig. 5 is a horizontal section through opective view showing one mg devices n released posite ends of the shiftable rod showing the manner of connection of the operating levers 1 thereto.

Referring in detail to the drawings, M

designates a series of mangers and W the front walls thereof. Each of these manger walls is centrally provided with an openin ,shown at 'w.

0 the inner face of each of the manger walls W, a casting is secured, said casting including spaced slde plates or flangeso integ'rally connected at one of their ends by the'body plate 6, which is engaged against the inner face of the manger wall and is provided with an opening which coincides with the opening w. The spaced side plates 5 of this casting are formed with laterally projecting flanges 8 having 0 enings there- 1n to receive suitable attaching screws '9. Said casting is also formed at one side'thereof and opposite the body plate 6 with a channeled extension 10, which is adapted to extend into a recess formed in the inner faceof the wall W, said extension having an apertured flange to receive an attaching screw 11. In the channel portion of the extension 10, an anti-friction roller 12 is retatably mounted, the axis of said roller being vertically disposed. The side plates 5 of.

the casting are provided with bolt receiving pon the inner face of one of the side plates 5, adjacent to the attaching flange 8, an inwardly projecting leaf spring 14 is secured purpose which will be presently stated.

l5 designates an axially shiftable rod, which is freelymovable through openings in the partition walls between the several mangers and also through one end wall of the stable. This shiftable rod is also loosely engaged through openings 16 provided in" y the side plates 5 of theseve'ral castings. At

one side of each 'of the metal castings secured to the manger wall, a yoke member 17 is engaged upon the-rod 15' Between the arms of the yoke, a collar or sleeve 18 is engaged upon said rod and is secured thereto against shifting movement b means of a cotter pin or key 19, whici is disposed through registering openings in the opposite sides of the sleeve and in the rod 15. Thus, the yoke member is held against longitudinal shifting movement on the rod. To

the end of said yoke member, a locking pin or bolt 20 is fixed and extends in parallel relation to the rod 15. This pin or bolt is engaged in the peripheral groove of the anti:

friction roller 12 and is adapted for. move-' the leaf spring 14. This spring acts to hold the rod against a casual, axial shifting movement when the bolt or pin 20 is disposed in its locking position through the openings 13, so that a positive longitudinal movement of the rod is required to move said pin to :1. released position. This pin 20 is adapted to engage through a sheave yoke or holder 22 in which the peripherally grooved roller or sheave 23 is mounted. The yoke member 22 is connected by a link-24 to a ring 25 to which the animal halter is adapted to be attached. The roller or sheave yoke and link 24 are inserted through the opening w in the manger wall from the exterior thereof and the pin or bolt' 20, when in locking position, is disposed between the roller 23 and the medial portion of the holder or yoke 22.

Each end of the rod 15 is longitudinally slotted or bifurcated, as at 26. Bearing members 27 and 28 respectively are secured in the opposite end walls of the barn or stable, and in the bearing member 27, a lever 29 is pivotally mounted intermediate of its ends. To the shorter end of this lever, one end of a link 30 is pivotally connected, as at 31, said end of the lever being movable through a slot or opening 32 in the barn wall. The other end of the link 30 is engaged in the slot or bifurcation 26 in one end of the rod 15 and is pivotally connected to' said rod at the inner end of said slot by means of the pin, indicated at 33. The other end of the lever 29 terminates in a convenient finger engaging hook 34. v

An operating lever 35 is also pivotally mounted at one of its ends in the other bearing member 28 and to this second lever,-at a oint in spaced relation to its pivoted end, a ink 36 is pivotally connected, as at 37 the other end of said link being engaged in the slot or bifurcation at the opposite end of the rod 15 and pivotally connected to the red at the inner end of said slot by the pin the animal halters.

38. The levers 29 and 35, when the pins 20 aredisposed in their locking positions, are seated in channels or grooves 39 and 40 respectively formed in the outer faces of the opposite end walls of the barn or stable.

In the operation of the device as above described, assuming that the several animals have been locked in their stalls by means of the invention in the manner above described, in case of fire or other imminent danger, when it is necessary to release the animals'so that they may effect their escape from the stalls, one of the levers 29 or 35 is ulled outwardly at its curved end. Assuming that the lever 29 is thus operated, it will beat once seen that through the medium of the link 30, the rod 15 will be axially shifted to the right against the holding action of the several springs 14.- and the locking pins 20 will be withdrawn from the openings 13 in the lefthand plates or flanges 5 of the respective metal castings until the extreme end of the pin is disposed in the opening in the other side plate. Thus, these pms are withdrawn from engagement with the sheaves or rollers 23, thereby releasin Such release is also e fected in a similar manner by operating the other of the levers 35. When this lever is pulled outwardly, the link 36, being connected to said lever intermediate of its ends, will pull the rod 15 to the right and thus retract the locking pins 20. .When one lever is moved to return the rod 15 to its former position, the other lever is similarly moved and both levers engaged in the grooves or channels 39 and 40 of the stable or barn walls. The series of leaf sprin s 11 engag ing in the grooves in the 1'0 15 securely hold said rod against any possibility of casual, shifting movement which might be occasioned by the pulling of the animals upon the halters. The rollers 12 and 23 assure the free and easy sliding movement of the locking pins 20 through the side plates 5 of the castings. In this manner, it will be seen that all of the animals within the barn or stable may be instantly released by the actuation of either of the operating levers.

From the fore oing description, taken in connection with the accompanying drawings, the construction, manner of operation and several advantages of my invention will be clearly and fully understood. The device consists of relatively few parts which are all of simple form and can be readily applied to the ordinary animal stall or manger without requiring material alterations therein and at relatively small expense. I have in particularly set forth, are susceptible of many changes in the form, proportionand construction thereof and I, accordingly, re-

serve the privilege of adopting all such legitimate changes asv may be fairly embodied within the spirit and scope ofthe invention as claimed.
